My 6400 will not transmit on SSB on 60M

Everything had been working fine on 60M for a long time. Today, the 6400 will not xmt on SSB on 60M. I have tried to go to the freq using either a pre programmed memory or directly from the VFO. Everything is fine on CW, but as soon as I switch to SSB the radio will not go into xmit. on the Maestro the PTT or the MOX or Tune buttons will not function. On the display of Smart SDR it shows TX not ready on the lower right of the screen, the PTT keys the radio but no output. What is interesting, If I just change the mode from SSB to CW it shows TX ready.

Any ideas where I should look?

    Same here, everything worked great untill i changed mic setting from the pr781 to the pr781ess. Now i have to hit the ATU before the mox or tune will become active. Some kind of Voo_Doo !

    Thanks, that was it. I had an wide SSB profile set for 80M, and it remained active when I switched to 60M.

    Using memories in FRstack has finally fixed my fumble fingers for this and several others.
